OPERATING AND FINANCIAL RESULTS

EWING, NJ, November 6, 2014 — Antares Pharma, Inc. (NASDAQ: ATRS) today reported operating and financial results for the third quarter ended September 30, 2014.

Quarter and Recent Highlights

• Increased the number of unique prescribers of OTREXUP™ to approximately 1,000 physicians at the end of the third quarter as compared to approximately 600 physicians at the end of the second quarter, according to Symphony Health Solutions.

• Generated approximately 9,000 prescriptions through September 30, with the total number of prescriptions in the third quarter increasing approximately 80 percent over the second quarter, according to Symphony Health Solutions.

• Reported total revenues of $6.6 million for the third quarter of 2014 and $18.1 million year-to-date. Net sales of OTREXUP based on patient prescriptions were $2.6 million for the third quarter of 2014 and $4.5 million year-to-date. In the first nine months of 2014, the Company shipped $6.4 million of OTREXUP to wholesalers.

• Ended the quarter with $48.1 million in cash and investments and no debt.

• Announced that the first and last patients were enrolled in a double-blind, multiple-dose, phase 3 study designed to evaluate the efficacy and safety of QuickShot^® testosterone (QS T) in adult males with testosterone deficiency. The enrollment period lasted three months and was completed ahead of schedule.

• Appointed Robert F. Apple to the newly created role of Executive Vice President, Chief Operating Officer. Mr. Apple will be responsible for all aspects of operations at Antares Pharma including sales, marketing, manufacturing and product development.

Eamonn P. Hobbs, President and Chief Executive Officer of the Company, stated, “The Company’s third quarter results showed continued, steady progress in the OTREXUP launch. The number of unique prescribers writing OTREXUP prescriptions and the total number of prescriptions generated in the third quarter increased significantly according to data received from Symphony Health Solutions. On the development side of the business, we were pleased to announce completion of enrollment in the QuickShot Testosterone study ahead of schedule. We believe that the study enrolled in half the expected time due to the level of interest in once weekly subcutaneous self-administration of testosterone.” Mr. Hobbs continued, “We are also pleased with the progress made this quarter in our collaboration business and anticipate beginning to fill pre-launch orders received from Teva for their generic epinephrine auto injector early next year.”

Third Quarter and First Nine Months Results

Total revenues were $6.6 million and $5.5 million for the three months ended September 30, 2014 and 2013, respectively, an increase of 19%. For the nine months ended September 30, 2014, the Company’s total revenue was $18.1 million compared to $15.9 million in the first nine months of 2013, an increase of 14%.

Product sales were $3.6 million in the third quarter of 2014 compared to $3.0 million in the third quarter of 2013. For the nine months ended September 30, 2014, product sales were $8.7 million compared to $10.1 million in the first nine months of the prior year. In the three and nine months ended September 30, 2014, the Company recognized net product sales of $2.6 million and $4.5 million, respectively, from sales of OTREXUP based on estimated patient prescriptions. OTREXUP revenue recognized is net of estimated wholesaler discounts, prompt pay discounts, rebates and patient discount programs. In the first nine months of 2014, the Company shipped $6.4 million of OTREXUP to wholesalers and deferred the difference between distributor sales and prescription sales. Sales of reusable needle-free injector devices and disposable components primarily to Ferring and Teva in the third quarters of 2014 and 2013 were $0.7 million and $1.0 million, respectively, and in the first nine months of 2014 and 2013 were $3.6 million and $2.8 million, respectively. Product sales in the third quarter and first nine months of 2013 included $2.1 million and $6.2 million, respectively, of initial sales to Teva of our Vibex™ auto injector for Teva’s generic epinephrine auto injector product, device sales that were not repeated during the same period in 2014. Product sales in the first nine months of 2014 and 2013 also included $0.6 million and $0.3 million, respectively, of sales of pre-commercial pen injector devices to Teva.

Development revenues were $1.7 million in the three-month period ended September 30, 2014, compared to $1.3 million in the prior year period. For the nine months ended September 30, 2014, the Company’s development revenue was $5.0 million compared to $2.7 million in the first nine months of 2013. The development revenue in each year was primarily due to auto injector and pen injector development work for Teva.

Licensing revenues were $0.9 million and $0.1 million in the three-month periods ended September 30, 2014 and 2013, respectively. For the first nine months of 2014, licensing revenues were $2.8 million compared to $0.2 million in the first nine months of 2013. The licensing revenue in the first nine months of 2014 was primarily due to revenue recognized in connection with our license and promotion agreement with LEO Pharma executed in November of 2013. The licensing revenue in the third quarter and first nine months of 2013 was primarily due to recognition of revenue deferred in prior years under agreements with Ferring.

Royalty revenues were $0.3 million in the three-month period ended September 30, 2014 compared to $1.1 million in the same period of the prior year. For the nine-month periods ended September 30, 2014 and 2013, royalty revenues were $1.6 million and $2.9 million, respectively. We receive royalties from Teva and Ferring related to needle-free injector device sales and/or hGH sales, from Actavis on sales of Gelnique, and from Meda Pharma on sales of Elestrin^®. The royalty revenue decreases were primarily the result of receiving no royalties from Teva in the second and third quarters of 2014 due to Teva’s recall of their hGH drug product Tev-Tropin^®.

Total gross profit was $4.1 million and $2.5 million in the third quarters of 2014 and 2013, respectively, and was $12.3 million for the first nine months of 2014 compared to $7.4 million for the first nine months of 2013. The increases were primarily the result of increases in development and licensing revenues.

Total operating expenses were approximately $11.2 million and $8.9 million for the three months ended September 30, 2014 and 2013, respectively, and were $37.4 million and $22.3 million for the nine months ended September 30, 2014 and 2013, respectively. The increases were primarily due to increased sales and marketing costs in connection with the launch of OTREXUP along with an increase in legal fees in connection with litigation.

Net loss per share was $0.05 in each of the third quarters of 2014 and 2013, and was $0.19 and $0.12 for the nine month periods ended September 30, 2014 and 2013, respectively.

At September 30, 2014, Antares had approximately $48.1 million in cash and investments, compared to approximately $69.1 million at December 31, 2013.
